I took the top off mine for a tank and didn't see any mpg difference. It actually seemed to lag more with the lid off. other than sound I'm not sure it's much of an improvement.. (I like the silent treatment/ sleeper look from my cars).

I didnt mean that it actually helped mileage, I meant that whatever minimal gains it gets from that (if there are any?) it is not much better to use a $250 aftermarket over just the ford cone.

I agree, anyone who thinks that this will actually do anything to help gas mileage or performance is HIGHLY mistaken haha. It just sounds cool

I think that best bang for your buck mods would be CAI, race header, 2.5" exhaust, with a tune. Unfortunately, I haven't found anything except the ford racing exhaust. It would be nice to see the ~200whp NA that I've found with 2zz-ge.

The engine responds well to mods , I 100% cannot stress enough that no mods need to be done till tuning comes out

This is a Diff ECU and a lot of new things on this engine that no one on this site has messed with I would be very carefull

Fuel pump driven off the cam , makes SERIOUS PSI change the fuel pump gears to make even more volume and psi , direction injection into the Cyl where the Inj wont have to be changed till about 450-500HP to the wheels and it goes on

There has to be more companies than SCT working on this. What about Cobb? Good thing about that is, Cobb is in Austin, dyno and all, so they would be able to handle every aspect of the tuning(and fine tuning) process.

I recently deleted the back muffler and replaced with some stainless steel pipe and a nice tip. I am very pleased with the sound as it gives a nice, deep somewhat loud sound but nothing too over the top. I am looking at intakes next, and i have a few questions in which i need advice. I dont want to replace the whole intake id rather just take the top off and drop in a cone filter. I am wondering if this has any positive effects as far as better MPG, sound, throttle response, and overall performance. Also by doing this would it void off any sort of warrantly since im just replacing the filter?
